Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property
damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions. Qualified
personnel are those who, based on their training and experience, are capable of identifying risks and avoiding
potential hazards when working with these products/systems.

Safety instructions 2
In the individual chapters of this document, you will find safety instructions that must be obeyed
absolutely, for your own safety, to protect other people and to avoid damage to property. Pay
attention to the following safety instructions for all activities on the inverter.

Safety information regarding the "Safe Torque Off / safe standstill" function (Page 56)
2.1 Warning symbol on the device
Please observe the warning symbols attached to the device. The warning symbols have the
following meaning:
Warning symbol Meaning
Warning: Voltage
Warning: Hot surface
General warning symbol: Observe the explanations about the hazard on the
device labels.
For transportation, observe the "transportation markings (Page 86)" on the device packaging.
2.2 Qualified personnel
The product/system described in this documentation may only be operated by personnel
qualified for the specific task in accordance with the relevant documentation for the specific
task, in particular its warning notices and safety instructions. Because of their training and
experience, qualified personnel can recognize any risks involved with handling these products/
systems and avoid any possible dangers.
2.3 The five safety rules
For your own personal safety and to prevent material damage when carrying out any work,
always observe the safety-relevant instructions and the following five safety rules according
to EN 50110‑1 "Working in a voltage-free state". Apply the five safety rules in the sequence
stated before starting work.
SINAMICS SM150 6SL3845-7NN46-7AA0
Operating Instructions 04/2017 17

Five safety rules
1. Disconnect the system.
Also disconnect the auxiliary circuits, for example, anti-condensation heating.
2. Secure against reconnection.
3. Verify absence of operating voltage.
4. Ground and short-circuit.
5. Provide protection against adjacent live parts.
To energize the system, apply the measures in reverse order.
2.4 Safe handling
WARNING
High voltages from external supplies
Even if the circuit breaker is open, parts of the drive can be under voltage (live) as a result of
the auxiliary voltage at the premagnetization, precharging or demagnetization transformers.
This danger is not limited to the drive, but can also occur with components that are electrically
connected to the drive (e.g. circuit breakers or isolators). Touching live parts can result in
death, serious injury, and damage to property.
● Isolate all components that can feed voltage to the converter before commencing work.
WARNING
High voltages during operation
When operating this equipment very high voltages develop. Even after switching off the mains
voltage, or while the connected machine is still turning, high voltages can remain for a
prolonged length of time. High voltages can cause death or serious injury if the safety rules
are not observed or if the equipment is handled incorrectly.
● Operate the drive properly.
● Always follow the "The five safety rules (Page 17)" when performing any work.
● Only remove the covers using the methods described by these operating instructions.
● Maintain the drive regularly and correctly.

18 Operating Instructions 04/2017

WARNING
Inactive safety functions
Inactive safety functions or ones that have not been adapted can result in machine
malfunctions. These malfunctions can result in death or severe injury.
● Comply with the safety instructions in Chapters "Safety instructions" and "Safe Torque
Off / Safe Standstill (Option K80) (Page 56)" before you commission the converter.
● Carry out a safety inspection for functions relevant to safety on the entire system, including
all safety-related components.
● Ensure that the safety functions used in your drives and automation tasks are adjusted
and activated using the appropriate parameterizing.
● Carry out a function test (Page 68).
● Only put your plant/system into live operation once you have ensured that the functions
relevant to safety are operating correctly.
WARNING
High voltages from machines still turning and connected
Rotating machinery can induce dangerous high voltages and synchronous motors that are
not de-excited immediately can also pose a hazard. If the connection to the motor is not
isolated or grounded, these voltages can also remain. Touching live parts can result in death
or serious injury.
● Before opening the doors, wait until the connected machine has come to a standstill.
WARNING
High voltages from DC link capacitors
High voltages are still present at the DC link capacitors even after shutdown. Touching live
parts can result in death or serious injury.
● A label on the converter specifies the discharge times of the DC link capacitors. Only open
the converter once these discharge times have expired.
● Observe the five safety rules when performing any work.
WARNING
High auxiliary voltages
High auxiliary voltages are still present even after shutdown. Touching live parts can result
in death or serious injury.
● Observe the five safety rules when performing any work.

SINAMICS SM150 6SL3845-7NN46-7AA0
Operating Instructions 04/2017 19

WARNING
Hazardous arcing
Hazards caused by arcing can occur as result of the following factors, for example:
● The input currents are exceeded
● Incorrectly dimensioned circuit breaker or transformers
● Incorrectly connected cables or cables that have not been connected
● Excessive pollution
Arcing can result in death, serious injury or material damage.
● Make sure that the system is properly dimensioned and that the power cables are correctly
connected. The maximum permissible input currents are listed in the "Technical
specifications".
● Remove any excessive pollution.
WARNING
Live, moving or rotating parts
Contact with the parts mentioned can result in death, serious physical injury or damage to
property.
● Observe the instructions regarding installation and operation.
● Always take protective measures before touching any components.
● Do not remove any necessary covers.
WARNING
Hot component surfaces
Certain components (e.g. heat sinks and reactors) can become very hot during operation.
These components can remain hot for a long time after operation. Contact can result in serious
injury, such as skin burns.
● Do not touch hot components even after you have switched off the drive.
CAUTION
Places that are difficult to access
If you do not use appropriate protective equipment when working in places that are difficult
to access you are at risk of injury. For example, sharp edges and splinters can cause injuries
to the head and skin. If you use unsuitable steps when working on the upper areas of the
drive, you can fall and injure yourself.
● Use appropriate protective equipment, especially a hard hat and gloves.
● In the upper areas of the drive, use suitable steps.
